WattStopper TS-400-W IntelliSwitch Digital Switch

The WattStopper TS-400-W IntelliSwitch Digital Switch is a low-voltage digital wall switch designed for use with WattStopper Digital Lighting Management (DLM) systems and operating on 120/277 VAC at 50/60 Hz through compatible DLM room controllers to provide programmable lighting control, scene selection, and load switching within a networked lighting management system. The unit, finished in white, mounts in a standard single-gang wall box and communicates over a low-voltage digital network, with LED status indicators that provide at-a-glance feedback on operation. It integrates with occupancy sensors, photosensors, and DLM controllers to support energy-efficient building operations in commercial environments. Typical applications include offices, conference rooms, classrooms, healthcare facilities, retail stores, government buildings, and educational institutions where digital lighting control and centralized building automation are required. Related replacements reflect its role within WattStopper/Legrand digital lighting ecosystems, including WattStopper LMSW-101-W Digital Wall Switch and Legrand Adorne Digital Lighting Switch.
